Sadie: Why I've given up on drinking

Meet the new Sadie Frost - fit, fresh-faced and sober in every sense of the word.

The once-notorious party girl says her days of hard drinking are over and her priorities are now charity work and motherhood.

Frost, 41, says her turnaround came after she visited an Aids housing project in South Africa this year. "It was the beginning of a new way of thinking for me. I analysed my life and began to appreciate it more than ever."

Inspired by the experience, she invited three South African orphanage workers to stay at her north London home.

"I had lots of things I wanted to do and the only way I could do everything was to get rid of something and I thought that should be drinking. Being sober has actually been easy for me." The mother of four,

formerly married to Jude Law and most recently linked to T4 presenter Alex Zane, 27, is also working on an ITV documentary, Extinct, and will travel to Borneo to highlight the plight of endangered orangutans. The series begins on 9 December.
